I ran dovecot -a and the blizzard of data seemed ok to my limited knowledge. Is there another log I should look into to trace this error down? <snip>

You should not be attempting to deliver mail to root directly. Instead you should forward root's mail to a real user with /etc/aliases; postfix's local(8) will not allow you to deliver mail as root.

The fix to this is simply not to deliver mail to root. You should have aliased root to a mortal user. Postfix will not invoke a mailbox_command as root.

In broader terms, you should only use root for actual system administration, and not for user tasks such as reading and sending mail.

See and edit /etc/aliases, then run "newaliases". Example:

root: thufir

http://www.postfix.org/postconf.5.html#default_privs http://www.postfix.org/postconf.5.html#mailbox_command http://www.postfix.org/local.8.html http://www.postfix.org/aliases.5.html

After you have done this, requeue the message:

# postsuper -r 35EC92A0D72

(or just delete it, s/-r/-d/, and try another test.)

Ah, thank you. Not dovecot at all, makes sense. I was sending to root because of a problem with keychain preventing usage of the "mail" command for users:

http://ubuntuforums.org/showthread.php?t=2065461

Anyhow, that's fixed so that I can now use the "mail" command as a mortal, as you put it. I think I'm on my way, and that this is a postfix and not dovecot problem. The mail doesn't arrive, but the log shows as delivered (I think) and then removed for some reason:
